Title: Method and apparatus for the transmission of speech signals
Inventor: MIKI TOSHIO
IPC: H04B1/46
Filed: 1992-10-26
Granted: 1997-09-16
Abstract: The present invention relates to a method of communicating a speech signal over a communication medium which utilizes what is called VOX (Voice Operated Transmitter) control and a speech signal transmitting unit and a speech signal receiving unit used in the method are disclosed.  The speech signal includes at least one speech-active duration in which an actual speech of the speech signal exists and one silent duration in which no actual speech of said speech signal exists.  At a transmitting side, the speech signal is analyzed for each of successive frames thereof to determine whether each frame is in the speech-active duration, and is coded for each of successive frames thereof to produce a series of successive coded data of the speech signal.  Then, in response to the detection of a speech starting frame of the speech-active duration, the coded data of the speech starting frame is switched to a preamble, and the preamble and the successive coded data subsequent to the speech starting frame are transmitted in the form of a series of successive frames. At a receiving side, the preamble is detected and the decoded results of the coded actual speech data subsequent to the detected preamble as a speech signal are provided.  When a predetermined number of successive coded actual speech data have been detected without having detected a preamble preceding thereto, it is decided that the decoded results of the coded actual speech data are in a speech-active duration and the decoded results are outputted as a speech signal.

Granted: 1998-10-06
Abstract: Package composed of part packs as well as process and apparatus for producing it.  Packages consisting of two part packs are in increasing demand as so-called cigarette sticks, because consumers want "half sticks", that is to say part packs having a smaller number of cigarette packs. The part packs are produced from a common one-piece blank which is severed before the package is put on sale, so that part packs formed from two part blanks are obtained.  These are connected to one another by means of severable connecting members, especially adhesive strips.  The mechanical high-performance production of such packages composed of two part packs is carried out in a folding turret.  A one-piece blank is introduced into pockets of the folding turret and almost ready-folded.  The groups of cigarette packs are then pushed via open sides into the part packs within the pockets.

Title: Method and apparatus for latent heat extraction
Inventor: EIERMANN KENNETH L
IPC: F25B29/00
Filed: 1992-11-10
Granted: 1996-03-12
Abstract: A method and apparatus for improved latent heat extraction combines a run-around coil system (WF) with a condenser heat rec-overy system (56) to enhance the moisture removing capability of a conventional vapor compression air conditioning unit (50). The run-around coil system (WF) exchanges ener-gy between the return (a) and supply air (d) flows of the air conditioning unit (10). Energy recovered in the condenser heat recovery sys-tem (56) is selectively combined with the run-around system energy extracted from the re-turn air flow (a) to reheat the supply air (d) stream for downstream humidity control. A control system (30) regulates the relative pro-portions of the extracted return air flow energy and recovered heat energy delivered to the re-heat coil (14) for efficient control over mois-ture in the supply air flow (d). Auxiliary ener-gy in the form of electric heat energy (60) is further added to the recovered heat energy for additional reheat use.

Abstract: A ski  tow arrangement  having  a  single  endless conveyor belt running on and directly supported by the snow, without the typical conveyor framing and idler rollers along the length of the belt.  Both the loaded and return belt run flat  on  the  snow,  side  by  side  with  adequate  lateral spacing, instead of the usual conveyor arrangement of loaded belt above the return belt.   At each terminal  four belt rollers, two horizontal and two vertical, serve to reverse the belt direction and provide adequate lateral  spacing.          Power is applied by conventional means to the head pulley of the uphill terminal.  The upper belt surface may be provided with cleats to hold the skier in position during slippery belt  conditions  on  steeper  slopes.     To   facilitate comfortable loading without a significant change in skier momentum,  a snow ramp allows the skier to accelerate to match the belt speed prior to arriving on the belt at the lower terminal.   Similarly the snow slopes away from the discharge end of the belt at the upper terminal to allow skiers to exit away from the ski belt and on down the hill by the force of gravity.

Title: Process and device for recycling blown plastics
Inventor: BACHER HELMUT
IPC: B29K105/04
Filed: 1993-04-26
Granted: 1998-11-17
Abstract: In a process for recycling blown plastics, the plastic is first ground, melted, and then is degassed and filtered. The degassed plastic is re-blown in the same plant before it has solidified, and, in order to make the degree of blowing uniform, the quantity of gas introduced into the plastic is controlled in relation to the quantity of plastic taken to the blowing plant per unit time, and the pressure of the plastic taken to the blowing plant is preferably kept as constant as possible. The device for implementing this process has an extruder to plasticize and degas the plastic, the outlet of which is connected via at least one line to a mixer to which a gas supply device is also connected. In the line there is a melt pump for the plastic, the flow rate of which is used as a guiding factor for the gas supply. The gas supply is provided via a device which is controlled by a control device in proportion to the running speed of the melt pump.

Abstract: A communicator station (60a) wirelessly transmits frames to and receives frames from at least one additional communicator (60b) in a Group in accordance with a MAC protocol. One of the communicators functions as a hub (64) and the remaining communicators function as remotes (66). The hub (64) sends control information to the remotes to establish repeating communication cycles, each of which has intervals during which the hub and the remotes transmit and receive frames. The intervals allow the hub (64) and the remotes (66) to anticipate transmitting and receiving frames, thereby allowing the remotes to power off their receivers and transmitters to achieve a considerable savings in power consumption without degrading communications. Other improved features include adjusting the intervals and the durations of transmission opportunities in the communication cycle to obtain the beneficial aspects of TDMA and PRMA for LAN-like communication without also incurring most of the undesirable aspects of such MAC techniques. Other control functions such as arbitration determine which communicator is better suited to act as the hub.
